PROBLEM TO BE SOLVED: To provide a voice notification device that can accurately notify a driver of a traveling vehicle of specific voice information effective to the vehicle.SOLUTION: There is provided a voice notification device 10 that notifies a driver of a traveling vehicle of specific information by voice, the voice notification device including: vehicle state detection means (imaging part 6, and vehicle state detection part 4) for detecting the position of a travel and travel speed of a vehicle; and control means (control part 3) for determining frequency deviation of a voice determined depending on the speed of the vehicle detected by the vehicle state detection means with the use of a predetermined calculation, converts the frequency of the voice to be input on the basis of the determined frequency deviation, modulates the voice after the conversion with an ultrasonic wave carrier, and emits the modulated voice to the position of the vehicle detected by the vehicle state detection means.
【課題】走行車両に対して有効な特定の音声情報を正確に報知可能な音声報知装置を提供する。【解決手段】走行車両の搭乗者に特定の情報を音声で報知する音声報知装置10であって、車両の走行位置と、走行速度とを検出する車両状態検出手段(撮像部6,車両状態検出部4)と、車両状態検出手段で検出した車両速度に依存して決まる音声の周波数偏移を所定の演算により求め、求めた周波数偏移に基づき、入力される音声を周波数変換し、変換後の音声を超音波キャリアで変調し、車両状態検出手段が検出した車両位置に向けて放射する制御手段(制御部3)と、を有する。【選択図】図1
